Explanation / Answer

(a) Calculating energy requirement ( NRC Method):

For adult dog-

BW = 40 lb = 18.16 kg

1. MBW = (BW).75= 8.8 kg

2.Energy requirement for ME = 130× MBW = 130×8.8 = 1144 per day

For Puppy-

current BW = 12 lb = 5.45 kg

1. MBW = (BW).75= (5.45).75= 3.56 kg

2. Energy requirement for ME :

(130× MBW)× 3.2× (e(-0.87p)-0.1)

p = current BW/estimated adult weight

= 5.45 kg/20.43 kg = 0.267

By putting value

energy req. = 1025.88 per day

(b) Calculating energy requirements ( kleiber RER method):

Fot adult

BW = 18.16 kg

MBW = 8.8 kg

Energy requirements for ME = 1.2× 70×MBW = 1.2×70×8.8 = 739.2 per day

For puppy-

BW= 5.45 kg

MBW= 3.56 kg

Energy requirement for ME= 3×70×MBW = 3×70×3.56 = 747.6 per day.
